Introduction: Overview

Overview

The target group for this service manual is the technicians who install and maintain the CDP

40-50-70 and CDP 40T-50T-70T dehumidier. Thus the manual covers instructions about

installation, operation and maintenance.

It is the responsibility of the operator to read and understand this service manual and other

information provided and to use the correct operating procedure.

Read the entire manual before the initial start-up of the unit. It is important to know the cor-

rect operating procedures for the unit and all safety precautions to prevent the possibility of

property damage and/or personal injury.

It is the responsibility of the installer to ensure the conformity of all, not supplied cables

towards national regulations.

Copying of this service manual, or part of it, is forbidden without prior written permission

from Dantherm.

Dantherm reserves the right to make changes and improvements to the product and the

service manual at any time without prior notice or obligation.

The unit is designed to last for many years. When the time comes for the unit to be recycled, it

should be recycled according to national rules and procedures to protect the environment.

The CDP dehumidiers contain R407C refrigerant and compressor oil. The compressor must

be returned to authorities for disposal according to local regulations.

This illustrates the functional principle of the CDP 40-50-70.

CDP

CDP -T

Fig. 1

CDP 40-50-70 and CDP 40T-50T-70T work in accordance with the condensation principle.

Humid air from the pool room is drawn into the unit by one or two fans.

When passing through the evaporator the air is cooled down to below dew point and water

vapour is condensed into water, which is drained.

The dry air is then passed through the condenser where it is heated and returned to the pool

room. As a result of the latent heat from the condensation process and the compressor en-

ergy the return air temperature to the pool room is approx. 5ºC higher than the air from the

pool room.

Air ow direction

Functionality of

the dehumidier

Product description: Overall description

When the dehumidier is started by the hygrostat, the fan(s) are activated at the same time as

the compressor.

In order to check the humidity level the units are starting the fan(s) once an hour for one

minute (NOTE: only applicable to CDP 40T-50T-70T units):

• If the humidity is above the selected setpoint, the unit starts dehumidifying.

• If the humidity is below the setpoint, the unit will remain o and check the humidity

level again after one hour.

To protect the compressor against overloading there is a timer which prevents the dehu-

midier from starting more than 10 times pr hour. It means, that there is at least 6 minutes

between every start up.

This unit is equipped with an intelligent defrosting strategy.

The unit monitors the temperature of the evaporator, and when the temperature has been

below a certain temperature for a period of time, the dehumidier will switch to active

defrosting, the fans will stop, and the magnetic valve will open.

The hot gas can now pass through the evaporator.

When the evaporator has the right temperature again the magnet valve will close and the

dehumidication will continue.

If the temperature in the dehumidier increases to a temperature of more than 55 °C (in case

of fan failure or room air temperature higher than 36 °C), the compressor stops automatically

to avoid damaging it. When the temperature allows it the dehumidication will continue.

Two cable grooves for accessory make it

easy to guide the cables from the control

panel to the mains electricity connection

and out of the unit.

Groove B is for use with cable from ex-

ternal RH sensor as it requires a seperate

groove to avoid interference.

All other accessory cables are to be

placed in groove A1-A2.

An LED is placed at the front of the unit. The LED light

indicates dierent modes of the unit.

Find a description of the dierent modes in section

“LED light and troubleshooting” on page 27.

The correct combination of chemicals in an indoor swimming pool is crucial, both for the

health of users and for the inventory inside the pool room and the swimming pool’s technical

room. Insuciently treated water results in poor hygiene, while water that has been exces-

sively treated results in gases in the air that contain chlorine, which can irritate the eyes and

cause breathing diculties.

At the same time, the incorrect composition of chemical ingredients in the water can destroy

all of the inventory in a very short space of time, including the dehumidier and other equip-

ment that have been installed to process the air.

Shown below are the threshold values, which apply to products for indoor swimming pools

in accordance with EN/ISO 12944-2, protection class C4. These threshold values must be com-

plied with for the warranty to be valid.

The following guideline values are applicable to swimming pools with the addition of chemi-

cals.

Chemicals ppm

Free chlorine content 1.0-2.0

Combined chlorine content Max. 1/3 of free chlorine content

pH 7.2-7.6

Total alkalinity 80-150

Calcium hardness 250-450

Total dissolved solids < 2000

Sulphates < 360

The following guideline values are applicable to swimming pools with self-production of

chlorine:

Chemicals ppm

Salt (NaCl) < 30,000

Total dissolved solids < 5500

pH 7.2-7.6

Total alkalinity 80-150

Calcium hardness 250-450

Sulphates < 360

It is advisable to use the Langelier Saturation index to ensure that the combination of the

dierent water parameters is acceptable.

Contact Dantherm A/S if necessary.

• The CDP 40T-50T-70T units are designed for installation in a heated room, adjacent to the

pool room.

• Do not place the dehumidier close to a heating source, e.g. a radiator.

• Doors and windows must be kept closed when the dehumidier is in function.

• To make sure that the room air passes freely through the dehumidier, air inlet and air

outlet openings must be free.

Risk of damaging the dehumidier, if it has been lying down.

The compressor can be damaged permanently, when the unit is started up just after it has

been lying down.

• Wait 1 hour with the start up of the dehumidier, if the unit has been lying down (e.g.

during transport or installation).

Risk of electric shock

An electric shock can cause severe burning and in most extreme cases shock to the brain,

strain to the heart, injury to other organs or result in death.

• Switch o the power on the main switch, while you open the dehumidier.

• Remember also to switch o the power, while you close the dehumidier.
